The present invention is directed to an apparatus and method of imaging and treatment using at least one photodynamic therapy ("PDT") agent. The method includes administering a photoactive agent to a patient (56), imaging the patient to locate the diseased tissue or tumors (54) in the patient using an imaging device (52) such as CAT scan or MRI, and treating the imaged diseased tissue with light (60) sufficient to photo-activate the agent in the tissue.
